WINDOW-SASH FASTENEB.

Specification of Letters Patent.

Application filed June 17, 1913. Serial Ito-1774318.

To all 1011077). it may concern:

Be it known that I, GEORGE G. ALTMAN, a citizen of the United States, residing in the city, county, and State of New York,

have invented certain new and useful Improvements 1n lVindow-Sash Fasteners, of

' which the following is a specification.

My invention relates to a window fastener and the main object of my invention is to provide a simple inexpensive means for locking the window, to prevent rattling and to support the sash when in open position.

Thevarious other objects .of the invention will be more fully set forth in the followingdescription of a. device embodying my invention, which consists in the 'new and novel features of construction and arrangement of parts hereinafter set forth and claimed.

In the accompanying drawing Figure 1 is a perspective view of a preferred embodiment ofmy invention; Fig. 2 is an elevational perspective view of a Window showing one of my fasteners in position supporting the window sash; Fig. 3 isa fragmentary view of a window frame showing my fastener in osition locking the sash and Fig. 4 is a simil iir view showing the fastener in one position to prevent rattlring of the sash. Fig. 5 is a fragmentary 'front 'elevation of the window casin showing another manner of applying the astener.

Describing the embodiment selected to disclose the invention there is shown an integral article preferably stamped to shape from a sheet of metal and bent into channel form illustrated. i

The fastener comprises an elongated back or body portion 1 extending preferably at right angles from opposite side edges 0t which is a pair of outstanding parallel flanges 2 forming an open end channel with the body portion *1. Each flange is of profastener in place and to provide a means to prevent the loss or misplacing of the device the same may be secured by a string engagmg the neck 4 of the head 5 which extends from the body 1 adjacent the broad end of the flanges 2. The opposite end of the body portion 1 is defined by a rounded nose 6 wlnch acts to facilitate the introduction of the wedge into narrow cracks between the sash and adjacent parts. v

A device such as described has numerous uses and as shown in Fig. 2 may be used as a wedge to support a sash in open position in case the sash c'ordis inoperative for any reason. As shown in' Fig. 3 the fastener may engage the frame, or one of the sashes, tolock the other sash immovably in position, or as shown in Fig. 4, may be disposed Patented May 5, 1914..

between the frame and sash to prevent rat- .tling and it is noted that, when the fasthe channel permits the disposition of the wedge in place with the sash cord in the channel thus forming a neat arrangement without presenting a. cutting edge to the sash cord.

It is obvious that this device is cheaply and easily-constructed, that there is but little loss of waste material and that it is capable of withstanding all strains incidental toa device intended for the purposes out-. lined.

It is apparent that many variations. of the device'herein described are within the skill of the mechanic as for instance a bearing surface and reinforcing rib may be formed by inturning the free edges 'of the flange2 and I therefore do not limit myself to the exact structure illustrated provided the means recited in the following claims be employed.

Having thus described my invention, -I claim 1. As an article of manufacture, an integral sheet'metal window sash fastener open at both ends comprising a flat body port-ion, parallel side flanges extending from said body portion to, form an open ended channel therewith and. adapted to have a sash cord positioned therein and extend in .a straight line in opposite directions therefrom, both (if said flanges decreasing in fording means for temporarily attaching said fastener to a Window frame.

2. An integral Window sash-fastener, comprising a sheet metal open ended channel shape wedge adapted to contain the sash cord within the channel and comprising a bottom member having a rounded nose at.

one end, side flanges inclined toward said rounded nose to form a wedge, and a prong extending from one of said flanges and in the plane thereof and spaced from the end adjacent said rounded, nose for fastening the wedge in place.

In witness whereof I have hereunto set my hand in the presence of two witnesses.

GEORGE G. ALTMAN.
